Application filed November 22, 1900. Serial No. 87,369. (No model.)

50 loom in the usual way. The devices for this Rock-shaft 12 is actuated from the main purpose are well known to those acquainted shaft 2 of the loom by suitable connections.

The devices for this purpose shown in the drawings consist of an arm or rod 17, rigidly secured at one end to the rock-shaft and at the other end engaging a crank-pin .18 on shaft 2, the crank-pin entering a longitudinal slot 19 in the rod 17. The purpose of this slot is to maintain the crank-pin in engagement with the rod 17 without interfering with the back-and-forth movement of thelay. The crank-pin has on it an autifriction-bushing or roller-sleeve to reduce friction. The rod 17 is preferably a two-part rod, the overlapping meeting ends of its two parts being provided with a series of holes 20 to receive the bolts and nuts 21, by which they are held rigidly together. By this means the working length of the rod can be adjusted to the distance between the main shaft and the lay in the particular loom to which the lay containing my improvements may be applied. The crank-pin 18 is adjustable both to and from the axis of the main shaft and also around said shaft. The former adjustment serves to regulate the throw of the crank, and consequently the extent of rocking movement of shaft 12, or, in other words, the extent of reciprocatory movement of the vertical needles. The latter adjustment is for the purpose of timing this movement of the said needles relatively to that of the lay and of the horizontal filling-inserting needles. To this end the crank-pin 18 is secured in acarrier 22, which is adjustable on shaft 2 and is provided with a slot 23, radial to the shaft, in which slot the crank-pin is seated and can be adjusted and held at any desired distance from the axis of the shaft. The carrier 22 itself can be moved around the axis of the shaft, being for this purpose preferably mounted so as to turn upon a center 24, coincident with the axis of the shaft, and it is held in the position to whichit may be adjusted by a set-screw 25 or its equivalent with whichit is provided, which enters and engages a slot 26 in a plate 27, secured to the shaft 2 or the drive-wheel 28 thereon,said slotbeing curved to conform to the arc of a circle struck from the point 24 as a center. In this way the two adjustments can be readily and accurately made.

My invention possesses marked advantages on the score of efficiency, economy, and simplicity over prior devices used for the purpose. There is a marked saving of power, friction, and vibration, less wear and tear on the loom, and the loom can be run at a higher speed without injury. An even greater advantage is the saving of cost and time in changing over narrow-ware looms to this system. Under my invention the entire change in construction is in the lay and its appurtenances. The lay with all its parts and the vertical needle-frame and all its operating appliances can be made in the machine-shop and can then be set up in place in the loom 6 without any change in the loom proper, all that is needed after the lay is in place in the loom being to adjust the length of the slotted rod 17 to the distance between the main shaft and the lay and'to put the crank-pin carrier 22 and the slotted plate 27 in place on the main shaft and after adjusting the crankpin so as to obtain the proper throw and timing to secure it in that adjusted position.

Having described my invention and the best way now known to me of carrying the same into efiect, Istate, in conclusion, that I do not confine myself narrowly to the structural details herein before set forth, since manifestly they can be varied to a considerable extent without departure from the invention; but

What I claim, and desire to secure by Letters Patent, is-

1. In a needle-loom, and in combination with the lay and main shaft, a vertically-reciprocatory loop engaging needle frame mounted on the lay, a rock-shaft mounted on and carried by the lay lengthwise of the same, connections between said rock-shaft and said frame whereby the rocking movement of said shaft causes the reciprocatory movement of said frame, a slotted arm or rod rigidly fixed to the rock-shaft,and a crank-pin on the driving-shaft engaging the said slotted arm, substantially as and for the purposes hereinbefore set forth.

2. In a needle-loom, and in combination with the lay and'the main shaft, a crank-pin carried by the driving-shaft and adjustable both to and from, and around, the axis of said shaft, a vertically-reciprocatory loop-engaging-needle frame mounted on the lay, a rockshaft mounted on and lengthwise of the lay, and operatively connected to the loop-engaging-needle frame, and connections between the rock-shaft and crank-pin whereby the rock-shaft is positively actuated in both directions, substantially as and for the purpose hereinbefore set forth.

3. In a needle-loom and in combination with the main shaft and lay, a vertically-reciprocatory loop engaging needle frame mounted on the lay, a rock-shaft mounted on and lengthwise of the lay and operatively connected to said frame, a crank-pin carried by the driving-shaft and adjustable relatively thereto, and a slotted two-part arm rigidly fixed to the rock-shaft and engaging the crank-pin, and adjustable in length, substantially as and for the-purpose hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 16th day of November, 1900.
